Plastic Optical Fiber(POF) tapered connectors can be used as the connection devices of POFs and quartz optical fibers,so this paper introduces the fabrication and performance of tapered POF connectors.A gravity vertical fused elongated taper method is used to fabricate the tapered POF connectors,and the optimal technical parameters are also obtained under the laboratory conditions.It is found that the process of POF stretching is easy to be controlled and the tapered POF connectors show its good optical quality when the control voltage is 6.0 V,the heating zone center temperature is about 214 ℃ and the stretch strength is about 1.40 g.Experiments prove that the transmission rate of the POF with a fine surface morphology decreases with increasing taper angles,its out light modes decreases,the out light mode intensity is on the low rank modes,and the losses from the visible light transmission spectrum increases in the ranges of 400 to 500 nm.These results show that the gravity vertical fused elongated taper is a effective way to fabricate the tapered POF connectors,and the obtained technical parameters from the experiments can provide the references for the actual productions of POF connectors or POF couplers.
